NEMIX RAM 128GB DDR5 6400 CL52 2Rx4 1.1V ECC RDIMM Supermicro H13SSL-N memory upgrade

SKU CH-QBW0-N2QVS

128 GB DDR5 6400 RDIMM with ECC and registered buffering, matched to Supermicro H13SSL-N for full-capacity stability

  • Capacity128GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 128 GB capacity lets the Supermicro H13SSL-N run fully populated at rated speed
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly
  • DDR5 6400 (PC5-51200) CL52 timing matches the board's memory-controller expectations exactly
  • 1 V operation at 2Rx4 rank keeps power draw within spec for dense server configs
  • 288-pin RDIMM form factor fits the H13SSL-N slots — not a UDIMM or SODIMM

Exact-match DDR5 server upgrade

This 128GB DDR5-6400 registered ECC RDIMM is built for the Supermicro H13SSL-N motherboard. It delivers the precise rank, voltage and timing the board's memory controller expects so the full capacity is recognised at rated speed. The module targets administrators who need maximum density per slot in a registered ECC configuration. Buyers who need unbuffered UDIMMs or non-ECC memory should look elsewhere.

Pre-installation checklist

Verify the H13SSL-N manual for approved DIMM population order and maximum supported capacity per channel before ordering. Confirm the server BIOS is updated to a version that supports DDR5-6400 registered modules at 1.1V. Ensure the chassis has 288-pin RDIMM slots and that no UDIMM or SODIMM variants are installed in the same channel. The module requires registered ECC architecture; systems without registered support will not boot.

Build and daily implications

The 288-pin registered form factor locks securely into the server board with standard ejector levers. No heat spreader is fitted, so airflow across the DIMM rows must follow the chassis design guidelines. Registered buffering reduces electrical load on the memory controller, allowing full population without signal degradation. ECC circuitry corrects single-bit errors in flight, helping prevent silent data corruption during continuous operation.

Perguntas sobre este artigo

Does the 128 GB DDR5 6400 kit ship as a single 288-pin RDIMM or do I need to buy extra modules?

The package contains one 128 GB DDR5 6400 CL52 2Rx4 1.1 V registered ECC RDIMM; no additional modules are required for a single-slot upgrade.

My board manual lists several DDR5 speeds — why choose the 6400 CL52 1.1 V 2Rx4 variant?

This exact speed, latency, voltage and rank combination matches the Supermicro H13SSL-N memory controller specification so the DIMM is recognised at full capacity and runs at its rated 6400 MT/s.

What does the 6400 MT/s rating deliver once the RDIMM is installed in a live server?

The module operates at DDR5 6400 (PC5 51200) with CL52 timing and 1.1 V, providing registered ECC bandwidth the platform expects for stable full-population operation.
